Sounds interesting. But processing power comparable to consoles 5-6 years old at this point is a bit of a letdown (supposed to be between a 360 and PS3). I imagine they'll have some interesting gimmicks with the touchscreen based controller then. It'll also be substantially outdated by whatever Sony and MS release next. A generational push that will probably happen sooner rather than later now, as MS hasn't forgotten the advantage they gained by going first (Sony is likely to take note, as well). Still, I think its cool that all the manufacturers seem to have found a measure of success and profitability this gen (some more than others) and the division is more evenly split - gives more power to the consumers this way.
Anyhoo, this leak was sourced from the same people who spilled the beans on the NGP, so its likely legit.
